Top 5 Best Episodes

Bump

S3 Ep 20 Digital Estate Planning – The group plays a video game that was developed over the course of thirty years, in response to a request made by Pierce in 1979 to get his father to invest in video games.

S3 Ep 3 Remedial Chaos Theory - When Jeff (Joel McHale) throws a die to determine who will go to collect the pizza delivery from downstairs, seven different timelines unfold, showing each of the group leaving to collect it depending on the outcome of the die.

S3 Ep 10 Regional Holiday Music - Through a series of events performed as songs, the members of the group are lured into joining the Glee club one by one.

S2 Ep 23-24 "A Fistful of Paintballs" and "For a Few Paintballs More."

S2 Ep 11 Abed's Uncontrollable Christmas – Stop motion animation.

I'd find this almost impossible. Each paintball episode has its own charm and glory, the pen/bottle episode is genius, the Halloween thing...there's too many.

My list would change daily, if not faster.

Any list I made, though, would almost certainly include the multiverse dice rolling and the dungeons & dragons one with Neil.
